Apollo Intelligent Dual IR Flame Detector

Summary

The XP95 Dual Infra-red (IR) Flame Detector is designed to protect areas where open flaming fires may be expected. It is sensitive to low-frequency, flickering infra-red radiation emitted by flames during combustion. The detector can operate even if the lens is contaminated by a layer of oil, dust, water-vapour, or ice. It is set to respond to low-frequency radiation at 1 to 15Hz (1 to 2.7μm) to detect all flickering flames, including those invisible to the naked eye, such as those emitted by hydrogen fires. The detector uses two IR sensors that respond to different IR wavelengths to discriminate between flames and spurious sources of radiation, avoiding false alarms due to factors like flickering sunlight through a combination of filters and signal processing techniques.
